Peanut paste is ground roasted peanuts with nothing else added, a thick, oily nut-paste base.
Dominated by a strong roasted-peanut aroma, with only faint natural sweetness and a light background bitterness; the body is heavy and oily rather than sharp.
Serving as a body-and-flavour base rather than a small seasoning, it thickens and enriches blended or shaken drinks and lends a roasted-nut aroma; the paste and its separated oil must be stirred back together before measuring.
Only another peanut product reproduces the roasted-peanut aroma and oily body — peanut butter (peanut paste plus additives) is the nearest, with its sweetness and salt adjusted out; where the paste is only a minor thickener, another ground nut or seed paste of similar fat content can stand in.
Peanut butter
Peanut paste is ground roasted peanuts alone, whereas peanut butter is characteristically that paste plus added stabilizer, sweetener, salt and/or emulsifier. In some markets the names were used interchangeably, so the two are not always kept distinct.
Peanut paste is obtained by roasting, blanching and grinding peanuts until they release their oil and form a paste. It carries no required ingredients of its own, and serves as the main component of some peanut butters, which add a stabilizer, sweetener, salt and sometimes an emulsifier on top of it.
Unstabilized paste separates as peanut oil rises to the top; keep sealed and stir the oil back in before use.
